Modelling a weir contained within a box culvert

[Stephanie S]

I am modelling a box culvert that has a weir halfway underneath it. There is a 1m drop between the upstream invert and the downstream invert of the culvert and therefore the height of the culvert is taller on the downstream side. How would you model this scenario in HEC-RAS? As a box culvert with a 1m drop on the downstream side, as a bridge with different upstream and downstream dimensions, or as an inline structure with a gate representing the culvert and weir? Thanks

Model it as cross sections with lids
